Iguanas look like green lizards with spikes running down their backs and a big white horn on the snout (a characteristic absent in the real-life animal). They have orange stripes on the back and a ligher shade of geen in the lowers side of the body. the belly appears to be light green or yellow.
They simply walk back and forth not interacting with the player. they can be defeated byany attack but not if hit with a spin attack in the side of the body where the horn is.
- There was supposed to be a mutant character based on an iguana, but subsequently the Naughty Dog team decided to make them regular non-mutant animal enemies.
